Answer and Step-by-step explanation:

The question gives you two functions: f(x) and g(x).

f(x) is given as an equation, and g(x) is given as a graph.

What the question is asking for is which function has a greater value than each other when the value of x is 3.

First, plug 3 into the f(x) equation.

f(3) = 3(3) + 1

f(3) = y = 10

Now, go to the x value of 3 on the graph of g(x). Follow the line up until your reach the line.

You'll see that on the graph of g(x), when x = 3, y (or g(3)) = 7.

f(3) = 10 > 7 = g(3)

This means that f(x) is greater than g(x) when x = 3.

So, A) f(x) is greater. is the answer.
